July and August are identical on tywiki
In mw.config.get('wgMonthNames') July and August are both "nō tiurai" on w:ty:. This is causing some unique problems. It's also like that in signatures. I assume the issue originates here, but where?
The translations here are different, and, while I don't know the language, common sense tells me that the translations here are probably correct.
They were incorrectly overridden locally on ty.wikipedia. I deleted the unnecessary local customizations. Can you please test there?
YES! It works now, thanks! The last piece of the puzzle for timestamp detection and conversion support for all Wikipedia language variants! :-)
